LIQUID-RECEPTACLE.

Application filed September 25, 1919. Serial No. 326,195.

To all whom it may concern:

Be'it known that I, I-IARRINGT N S. Ban- ROWS, a citizen of the United States, residing at Lee and Mayfield Roads, 1n the clty of Cleveland, county of Cuyahoga, and State of ()hio, have'invented a new and useful Improvement in Liquid-Receptacles, of which the following is a specificat on, the principle of the invention being herein explained and the best mode 1n which I have contemplated applying that principle, so as to distinguish it from other invent ons.

My invention relatesto a 'llqllld receptacle and more particularly to a d1sh or container with a plurality of peculiarly relatet compartments each of which is intended to receive a different liquid and at least one of which is to be kept hermetically sealed by means of a detachable cover.

In the practice of dentistry precious metal, for example gold, must be cleaned I prior to insertion into a tooth cavity and such cleaning is ordinarily effected by clipping the gold into a strong acid the fumes of which are destructive. It therefore becomes necessary subsequently to neutralize any acid adhering to the gold prior to insertion into the mouth of the patient. For thi purpose an alkali such as soda is employed and finally the gold is rinsed by dipping the same into water. It is desirable therefore tohave the three liquids, namely, the acid, the alkali and the water, ready to hand and accordingly, a dish embodying my invention is purposed to contain these three liquids. It is important that the acid compartment be kept hermetically sealed except momentarily when the gold is to be dipped therein and it is furthermore desirable to have the three liquids close together to enable that the successive dipping from one to the other in the order already mentioned with a minimum of effort and loss of time prior to fitting of the gold into the tooth. Moreover, it is preferable to so shape the dish that the successive dipping operations may be performed without allowing drops to fall beyond the confines of the dish until after the gold has been rinsed in water.

Consonantly, the object of my invention is to provide a dish adapted to serve as part of dental equipment and to permit of ready access to a plurality of liquids including an acid the fumes of which, if allowed to escape, will injuriously affect metal such as that of the tools'employed by a dentist or rust any other metal objects exposed thereto. A further object is to provide the acid compartment with a relatively small opening adapted to be hermetically sealed as by means of a ground glass fit. Such an 7 adapted equally well to the jewelers trade and doubtless to other industrial shops in which the cleansing of precious metals by means of an acid bath is regularly practised.

Adverting to the drawing Figure I is a top plan view of a receptacle embodying my invention; the cover having been removed. U

Fig. II is a vertical section on zig-zag line II-II of Fig. I for the additional cover likewise shown in section and showing an interior stopper appearing in elevation.

Fig. III is a plan section on line III-III of Fig. II looking downwardly.

The receptacle, which may be composed of moldable material such as porcelain or glass, comprises a bowl 1 and extending upwardly interiorly thereof is a partition 2 having three radial extensions 3, 4 and 5 respectively which together divide the bowl 1 into three substantial equi-sized compartments. Such compartments are purposed to contain one an acid, the other a soda and the third water.

Owing to the destructiveness of the fumes of the acid usually employed for the cleansing of precious metals, and specifically because the fumes of the acid readily attack the nickel-plated coating of instruments and Specification of Letters Patent. Patented June 15, 1920. I

thus eventually cause them to rust, it becomes desirable if not indeed necessary to keep the acid hermetically sealed except during the few moments which elapse while the.

tegral top 6 having an upper surface 7 depressed relative to the top of the partition "2 and also relative to the upper rim of the bowl 1. At its middle the top 6 is fashioned with a tapered hole 8 adapted to snugly receive a ground glass stopper 9. Over the receptacle including its three compartments is a cover 10.

It is clear that the stopper 9 enables the acid compartment to be hermetically sealed and thereby precludes the rusting of metal implements which might otherwise be exposed to an attack by the acid fumes. At the same time the other two compartments, which it is required to have readily accessible inorder first to neutralize the acid coat-V necessitating its manual conveyance beyond the outermost confines of the receptacle prior to the last act of dipping into the water. In this manner all the dipping operations may be performed without allowing destructive drops to fall outside of the ceptacle to be grasped so that the fingers engage the bottom while the thumb engages the top of the stopper thereby enabling the receptacle to be inverted and the soda and water emptied without permitting the escape of any acid.

I claim A device of the character described comprising as an integral construction a hollowed piece of vitreous material divided by upright partitions into' a plurality of laterally adjacent compartments each open above but having nocommunication with each other, one of which includes an integral cover provided with a hole, a stopper for hermetically sealing said hole, and a cover for the entire receptacle adapted directly by itself to extend over to close all of said compartments and to inclose said stopper.
